Anyone out there have problems with GDP’s tuning on a 17 Titan XD Pro4x? Just hit 108k miles. I’ve installed the EZ lynk programmer no SOFT and have some weird issues. Set up: EGR intact, DPF removed. first issue: loaded 120hp v1.8 profile and truck ran fine day 1 no WOT. Day 2 drove truck 15 minutes still no WOT, shut down, started truck remotely then heard the engine lope like it was losing fuel pressure. Immediately cut the truck off, restarted with ignition, truck loped then shut off on its own. Primed fuel system, started and was able to get home. DTC showed U1300, U1266. Cleared fault installed 0hp v2.2, boost appears to be scavenging low pressure and high pressure turbos around 75mph, no fuel pressure issues. I have zero help from GDP as they state they have 1000s of trucks with these profiles and no issues. Reinstalled DPF system, returned to stock profile and boost seems normal, no fuel pressure issues. Flashed 0hp tune DPF/EGR installed/disconnected same boost failure but no fuel pressure issues (decided to rule out fueling). All tunes minus returning to stock appears to be scavenging for boost between low/high pressure turbos around 75mph. If I WOT the truck with any tune other than stock it pops a coolant flow restricted DTC P00B7 and puts the truck in limp mode (engine power reduced).
